Solve 5*10^6=pi*(86.5)^2*h

$$5 \times 10 ^ { 6 } = \pi \times ( 86.5 ) ^ { 2 } \times h$$

Solve for h

$$h = \frac{20000000}{29929 \pi} \approx 212.710004466$$

Steps for Solving Linear Equation

Calculate 10 to the power of 6 and get 1000000.

$$5\times 1000000=\pi \times 86.5^{2}h$$

Multiply 5 and 1000000 to get 5000000.

$$5000000=\pi \times 86.5^{2}h$$

Calculate 86.5 to the power of 2 and get 7482.25.

$$5000000=\pi \times 7482.25h$$

Swap sides so that all variable terms are on the left hand side.

$$\pi \times 7482.25h=5000000$$

The equation is in standard form.

$$\frac{29929\pi }{4}h=5000000$$

Divide both sides by 7482.25\pi .

$$\frac{4\times \frac{29929\pi }{4}h}{29929\pi }=\frac{4\times 5000000}{29929\pi }$$

Dividing by 7482.25\pi undoes the multiplication by 7482.25\pi .

$$h=\frac{4\times 5000000}{29929\pi }$$

Divide 5000000 by 7482.25\pi .

$$h=\frac{20000000}{29929\pi }$$
